Magnetic Materials

2:45 PM-4:45 PM
Room: Liberty C

Magnetic materials display a rich spectrum of microstructures. They also serve as excellent materials for the study of phase transitions as modeled by Ginzburg-Landau theories. From ferromagnets to high T_c superconductors, these materials continue to be of great technological importance. The goal of this minisymposium is to discuss several new developments; focusing on three interacting themes - mathematical analysis, numerical simulations, and experimental observations. In particular, the speakers will discuss the simulation of magnetization reversal, the analysis and simulation of magnetic domains and walls observed in ferromagnets and during the intermediate state of a type-I superconductor, and the analysis behind new models for high T_c superconductors.
